Robot ultrasonic welding system capable of achieving grid and spoiler sharing

Abstract

The invention discloses a robot ultrasonic welding system capable of achieving grid and spoiler sharing. The robot ultrasonic welding system comprises a control box, a frame, a front grid jig trolley,a front lower grid jig trolley and a spoiler jig trolley. A trolley entering concave cavity and a locking device are arranged on the front side of the frame. Two mechanical arms are mounted beside the trolley entering concave cavity. A rotating block is mounted at the tail end of each mechanical arm. At least one welding joint is arranged on each rotating block. Action and the operation track ofthe mechanical arms are controlled by the control box. According to the robot ultrasonic welding system, the two mechanical arms are used for welding products at the same time, and the takt of a single kind of products is improved to 60 PCS / H from 20 PCS / H; three kinds of products are universal for one kind of equipment; personnel are reduced, and the number of the personnel is reduced to one fromthree; and the operation labor intensity of the personnel is reduced, and hurt of harmful gas and noise to the human body is reduced.

Description

technical field [0001] The invention relates to a welding device in the field of auto parts production and research, in particular to a robotic ultrasonic welding system capable of sharing grids and spoilers. Background technique [0002] Among auto parts, the front grille, front lower grille and spoiler all need ultrasonic welding brackets on their bodies. Specifically, in the welding production of the front grille, two front grille brackets will be welded in the middle of the front grille body. The front grille brackets are symmetrical on the front grille body. Realization; in the grid welding production of the front lower grid, the first bracket and the second bracket will be welded on the upper and lower sides of the front grid body respectively, and the first bracket and the second bracket occupy most of the sides where they are located. Generally speaking, The welding spots are welded sequentially through the special front and lower grille ultrasonic equipment; in the...

AI Technical Summary

Problems solved by technology

Since the front grille ultrasonic welding equipment, front lower grille ultrasonic welding equipment and spoiler ultrasonic welding equipment are all special welding equipment, the position of the welding unit cannot be adjusted. Therefore, it is impossible to replace the corresponding different positioning fixtures in time. Weld other parts

Therefore, the existing production method has the following problems: the grille and the spoiler require 3 operators and 3 manual ultrasonic welding machines; the daily beat of the equipment is low (20PCS / H); the manual operation is labor intensive, The smell and noise generated by close-range operation are harmful to the human body
